De Vries, Cramer, Babcock, Bailey, Castle, Collins, Cook, Dorsey, Galloway, 

 Kearney, Shull, Stout, Swingle, and Webber. Of the men who have been more 

 particularly concerned in the introduction and development of commercial bud 

 selection work, the following names may be mentioned: Powell, Burbank, Fraser, 

 Chase, Winberg, Farmer, Coates, and Milliken. To this list many other names 

 of important workers might be added, but the writer considers that sufficient 

 names have been given to indicate the type of workers concerned in this work. 



SUMMARY. 



The fundamental factors in the economic work for the improvement of 

 plants through bud selection are (1) the development of new and important 

 varieties originating from bud mutations; (2) the isolation of valuable strains 

 of established varieties originating as bud variations; and (3) the amelioration 

 of the cultivated varieties and strains by bringing up their average production to 

 as nearly that of the best individuals in them as may prove to be possible through 

 the systematic selection and propagation of superior parent plants. 



The experience and achievements to date in both the investigational and 

 commercial work for the improvement of plants through bud selection, warrant 

 the belief that much greater progress along these lines may be expected in the 

 future than has been accomplished in the past, when the possibilities of this work 

 become more generally recognized and more fully understood. 



The writer believes that in the plants with which he is familiar, asexual and 

 sexual reproduction are fundamentally alike in respect to the extent and range 

 of variation, and that equally valuable results have been achieved and may be 

 expected in the way of plant improvement from bud selection as has been the 

 case with seed selection.
